How often must fire extinguishers in the barracks be checked for serviceability?

Fire extinguishers in the barracks must be inspected for serviceability once a month. This monthly check ensures that all extinguishers are in proper working order, fully charged, and readily accessible in case of an emergency. During these inspections, personnel should look for any visible signs of damage, check pressure gauges, and ensure that the extinguishers are not obstructed. Proper maintenance and regular checks are critical for ensuring safety within the barracks, as they allow for immediate response capabilities during a fire situation.

The other options indicate different frequencies of inspection that do not meet the Army's standards for safety and readiness. Weekly inspections might be overly frequent and impractical for most units, while checking every six months or yearly increases the risk of undetected issues that could render the extinguishers ineffective when needed most.
